This adds a class CanonicalName that can represent a library, class, or member. All references now go through a Reference object, which is linked to both the AST node and its CanonicalName, so either can be created first. dartk now accepts multiple input files: - If multiple dart files are given, they are all compiled. - If multiple binaries are given, they are linked together. Mixed dart and binary input is not supported by dartk. dartk now has a flag --include-sdk which includes the entire SDK in the output. This is so the SDK can be compiled alone and then linked. Example of compiling separately and then linking: dartk foo.dart -o foo.dill dartk main.dart -o main.dill dartk --include-sdk -o sdk.dill dartk main.dill foo.dill sdk.dill --target=vm --link -o program.dill dartk still has incredibly slow cold start due to the analyzer loading the dart sdk, so this does not actually speed things up at the moment.
